provide a motor vehicle ofsuch special and.

particular construction and arrangementof to or connecting therewith oneor more agricultural machlnes, and as to afford unusual power forpropelling the vehicle and such machine or machines as may 'be attached.

thereto,

A further object of the invention is to rovide certain driving mechanismin a 'our-wheel motor vehicle, special steering mechanism, and specialconnections between said d'rlving mechanism and sa1d steering mechanism,for the purpose of expedi tiously combining and operating the; same byor through the operation of the vehicle and while-the latter ispropelled.

A still further object of the invention is to provide novel and peculiarmeans for operating an endless drive chain during its driving operationto reverse the drive and to change or vary the speed or driving power ofthe chain as desired.

A still-further object of the invention is to provide certain details ofnovel-and peculiar construction in the various parts and theirconnections as will be hereinafter fully dc axle. V Guide sheaves orrollers Qtikeep the scribed.

Various other objects, advantages and improved results will be found inthe practical application of the invention.

In the accompanying drawings forming part of this application: Figure 1is a side elevation of the machine showing cultivators attached theretoand operated thereby. Fig. 2 is an enlarged sectional view. Fig. 3 is alongitudinal sectional view. v

The same reference characters denotethe same parts throughout theseveral-views of the drawings.

The motor vehicle shown in the drawings and hereinafter to beparticularly described, has an engine 1 mounted on the bed 2, foroperating an endless drive chain 3, which drives. the front and rearwheels 4 and 5, re-

spectively. of the vehicle through medium of front and rear sprocketwheels 6 and 7 centrally mounted, respectively, on the frontaxle- 8 andthe rear axle 9 of the vehicle. Said axles being sectional. The engineshaft 10 is provided with a sprocket wheel 11 for the chain 3, and alike sprocket wheel,

12 for the chain is'mounted on a shaft 13, provided with a gear 14 andmeshing with a gear 15 on the engine'sh'aft 10. The chain passes overthe sprocket wheel 11 and over the sprocket wheel 12, whereby the chainis driven for forward movementof the vehicle by the sprockets 11 and 12so that there is a double drive of the chain between the saidsprocketwheels 11 and 12 and the traction- Wheel sprocketsxti and 7. Thesaid sprockets 11 and.12 are thrown in and out of chain driving positionby clutches 16 and 17 operated'by clutch levers18- and 19 respectively,and said levers are operated by a hand lever 20. V

One of the more important features of my invention isthe means forautomatically reversing and changing the speed of the vehicle and the.driving power of the traction wheels. This I accomplish by a pair ofsprocket wheels 21, mounted on a shaft 22, having a gear wheel 23meshing with the gear wheel 14. The sprockets 21 are coupled -anduncoupled with the shaft 22, by means of a pair of clutches 24, operatedby clutch levers 25. The chain 3 passes from the sprocket 11 to one ofthe sprockets 21 thence over the sprocket wheel on the front axle, thenback to and over the other of the sprockets 21, thence over the sprocket12, and around the sprocket wheel of the rear chain 3'in mesh with thesprockets 11 and 21. It is obvious that thc vehicle is propelled forwardby the sprockets 11- and 12 operating the chain 3, that the movement. of

-the vehicle is reversed by operating the the r ion 32 is slidably keyedto a.v shaft 33, for meshing with the segments and the pinion isoperated by a lever 34 to slide the pinion into mesh with one or theother of the segments as desired; the shaft 33 is operated by astand-shaft 35 having a hand wheel 36 and connected with a shaft 37 bygears 38, and the shaft 37 is connected with the shaft by means; of auniversal joint 39, The axles have skein or casing 40, and the axles areCOIlnGCti-ll with the Wheel spindles 44 by universal couplin' s 45.

The traction w eels 4 and are all of the same ctmstzuction, thereforeonly one of them will he described in detail. Such wheel has a series ofcross-plates'46 secured to and bet. eon the wheel-rims 46 and theseplates U1. aced apart by brace plates 47 so as to form pockets 47. Theobject of this particular ieel construction is to furnish a wheel tr adwhich will enter the earth or ground and thus avoid packing the earthand slipping of the wheel.

The vehicle being especially adapted for operating agriculturalmachines, I have shown a. gang plow 48,21 harrow 49, and a gang art 5 indrill disks 50 connected with the vehicle Althoug'i I'have shown anddescribed the motor 'veliicle in connectionwithv and for operatingcertain agricultural machines or implements, it must be understood thatI do not limit or confine myself to vany particular use or applicationof the vehicle, nor

Neither do I Wish tobe underasrestricting the invention to any parl sizz -shape or material in theconu on hereof, or in constructions there- 7301' to the particulardetails employed n, llilireserve to myself the right to snch applicationof the vehicle as may it. found possible or desirable, aud t-o use (hmechanical equivalents in the manu- "11 of the vehicle and the variousparts and in means for connecting it with chines as may be foundexpedient, parting from the scope of the apunis.
